STOVE.

SPECIFICATION forming part of Letters Patent No. 247,154, datedSeptember 20, 1881, Application filed March 21, 1881. Nb model.)

To all whom it may concern:

Be it known that I, LEWIS F. BETTS, of Morton, in the county of Delawareand State of Pennsylvania, have invented certain new and usefulImprovements in Stoves, of which the following is a full, clear, andexact description,

reference being had to the accompanyingdrawings, and to the letters ofreference marked thereon.

My invention has special relation to that class of stoves used fordomestic purposes wherein hydrocarbon oils are employed asfuel, and inwhich the escape for the products of combustion is located at that partof the struct- 1 ure most remote from the source of heat or point ofignition, and has for its object the production of an effective andsimple device, in which the arrangement of constituent parts is suchthat the air for the support of combustion is admitted to the burnersthrough an inlet or inlets in close proximity thereto, but in suchmanner that the supply will be steady and uniform,in order to promotethorough and perfect combustion. To accomplish this, my inventionconsists, essentially,in surrounding the burners with a device forregulating the supply of air thereto, the discharge-opening at theextremity of the passage for the heated products of combustion being soarranged as to expedite their outflow, thereby rapidly drawing in asupply of fresh air to the burners to feed the flame; and my inventionconsists in certain novel anduseful combinations or arrangements ofparts and peculiarities of construction and operation,all of which willbe hereinafterfirstfully described, and then pointed out in the claims.

' In the drawings,Figure1is a side elevation and partial section of oneform of stove constructed in accordance with my improvements, showingone mode of supplying air to the burners. Fig. 2 is a plan view of theoil pot and burners employed in the stove shown in Fig. 1. Fig. 3 isside elevation and partial section of a double stove. Fig. 4 is anenlarged sectional view of the burner shown in Fig. 1, illustrating thearrangement of the parts.

Like letters of reference,wherever they occur,

indicate corresponding parts in all the figures,

A is the base of the stove, constructed of cast-iron or any othersuitable material.

B is the oil pot or reservoir, extending a part of or the entire lengthof the stove. Said oilpot may be formed of tin or other preferredmaterial, and secured to the base A, or wholly or in part casttherewith, forming a portion of the same.

0 are burners 'of any approved style,having proper connection with theoil-pot.

E is a chimney surroundingtheburners, and extending to sufficient heightthereabove to insure perfect and complete combustion.

D is the top plate, perforated with any desired number of utensil-holes,said plate being located upon a base, D, of suflicient depth to permitthe bottoms of cooking utensils to extend a distance below the top plateD, and cast in such manner as, with plate D, to form a confined passagefor the heated products of combustion from chimney E to the exit E,provided for the same. The top of the stove may be firmly held in placeupon the chimney by means of suitable rods extending through the chimneyfrom plate D to the base of the stove, or in any other preferred manner.

F is a standard supporting the other extremity of the stove top and baseD.

E is the outlet for the products of combustion, the same being soarranged that passing currents of air will serve to increase theoutflow, and from its peculiar construction any possibility of currentsentering the outlet and causing a back-draft is obviated.

In Fig. 1 is shown a stove wherein the air for the support of combustionis supplied directly to the burners from a point upon or near a levelwith the top of the wick-tubes.

b is a plate surrounding the wick-tubes, upon which rests chimney E. Theedges of this plate are turned downwardly at each side, leavin g an openpassage thereunder to the burners. Surrounding the burners is a jacket,H, placed atadistancefrom chimney E and plate I). Said jacket extendsfrom the oil pot or from a plate, b, located a short distancethereabove, t'o'.a point about upon aplane with theburner-cones, and isopen at the top. Perforations t mayibe placed in jacket H, extendingfrom'the top thereof to the plane of plate b. Upon the interior ofjacket H may be placed one or more partitions, h, extending from thebottom of jacket H to a short distance above the top thereof, saidpartitions h extending beneath the burner-cones entirely across thespace inclosed by jacket H, my said invention being an improvement uponthe devices shown in Patent No. 238,395, granted to J. H. Irwin March 1,1881, (lamp stoves,) wherein are shown vertical strips placed againstthe chimney, forming a support at top for cooking utensils, butextending downward only to the flange upon the burner-cones. Currents ofair entering the perforations or passing over the top of jacket H, andstriking the chimney and flange upon plate I), will be deflecteddownwardly under the plate, and from thence up into the burners. By useof the partitions, no matter from what direction impinging currents maycome, they will be deflected thereby in such manner as to promote andaccelerate combustion.

The outlet E for the products of combustion in stoves of theconstruction shown in Fig. 1 is located at the end of the heat chamberorpassage oppositeto the chimney. Itis placed upon the under side ofsaid chamber, so that the products of combustion will be compelled topass downward in order to escape. Any disturbance of the extraneousatmosphere serves to increase the outflow, thereby promoting combustionat the burners by reason of the increased draft.

In Fig. 1 the direction of the fresh-air currents is indicated by thesharp-headed arrows,

' and the products of combustion by those having round or blunt heads.

Upon the top of support F are placed arms f, secured to the edges ofoutlet E, said arms being of such size as not to interfere with theoperation of the stove. If desired, instead of locating a single supportin the center of the outlet, two may be used, one upon each side,thereby giving greater strength and solidity to the structure.

For convenience in use, a light shelf, a, constructed of perforatedmetal, wire, or any preferred material, may be located between theoil-pot and top of the stove, as shown. This shelf rests upon a bracketor brackets on support F, and upon the top ofjacket H, or suitablebrackets on chimney E. If required, several shelves may be employed, thesame being made removable from the stove, and in no wise interferingwith the operation thereof. In practice they will be foun d of greatconvenience, serving as a receptacle for cooking utensils when not inuse, as a space for the purpose of keeping articles of food warm whennot immediately required, and as a desirable place to setfbread, &c., toraise before baking.

Fig. 3 shows a double stove, which may be constructed upon the sameprinciples and operate the same as that shown in Fig. 1, the essentialdifference being in the provision of two or more hot-air spaces orpassages, with an outlet for the products of combustion at the extremityof each, the burner or burners being located midway between saidoutlets, and in the use of a series of flanges or divisions, M, aroundthe burners. These divisions extend beneath the burner-cones and down tothe top of the oil-pot, or to a suitable plate located thereabove, andmay be carried up upon the exterior of the chimney to the bottom of baseD, as indicated by the dotted lines, Fig. 3, or to any desired heightabove the plane of the burner-cones.

m is a perforated band extending at an angle from the flange upon plateI) to the oil-pot or support of the flanges M. Currents of air strikingthese divisions or flanges and the chimney will be deflected to theunder side of the burner-cones, and by passing through the perforationsin band an will feed the flame in a substantially uniform and regularmanner. This large form of stove, with any of the airregulating devicesapplied thereto, is desirable where great heating-surface or large spacefor cooking utensils is required.

At a convenient point in the chimney of the stove may be placed a doorof suitable size and construction, for the purpose of trimming thewicks, lighting the same, or for reaching the burners for any otherpurpose, and each oil-pot should be provided with a filler of anyapproved pattern, for the purpose of supplying the burning-fluid.

Stoves of any size may be constructed in accordance with the foregoingdescriptions, and they will be found to admirably answer the varioususes and purposes for which they are intended. The locations andarrangement of the inlets for fresh air and the outlets for the productsof combustion are such that the stove may be placed in a draft orcurrent of air or used in any exposed position, such currents or draftsserving to promote rather than retard combustion, thus preventingsmoking.

Having now fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is-

1. In a stove of the character herein specitied, the combination, withthe burners O, of plate I), partitions h, extending beneath theburner-cones, and the jacket H, surrounding the burners and base of thechimney at some distance therefrom, the top of said jacket being locatednearly upon a level with the burner-cones, substantially as shown anddescribed.

2. In a stove of the character herein specified, the combination, withburners O, ofjacket H, closed at bottom and perforated at its upperedge, and the partitions h, extending beneath the burner-cones,substantially as shown and described.

3. The combination, with the burners of an oil-stove surrounded by ajacket open at top,

of the partitions located in said jacket, said partitions extendingslightly above the jacket and beneath the burner-cones, the wholeforming fresh-air conduits to the under side of the burner-cones,adapted and arranged to conduct fresh air thereto to support combustion,substantially as shown and described.

4. In a stove of the character herein specified, the combination, withthe straight jacket H, closed at bottom and open at top, said jacketbeing perforated at its upper edge, of the partitions located in saidjacket, extending beneath the burner-cones and slightly above thejacket, substantially as shown and described.

5. In a stove of the character herein specifled, the flanges ordivisions located upon the outside of the burners, extending beneath theburner-cones and from the oil-pot above the burners upon the exterior ofthe chimney, substantially as and for the uses and purposes shown anddescribed.
